head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Arcade run-and-gun reflexes against fully memorisable boss patterns.

Execution · Pure Mechanics
A skateboarding game about chaining trick combos across stylized levels.
Sunset Riders leans Execution (Pure Mechanics); Tony Hawk's Pro Skater 5 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sunset Riders
Dodging bullet spreads and snap-shooting bosses is everything
Tony Hawk's Pro Skater 5
trick-combo timing and balance execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sunset Riders
Bandits and bosses cycle memorisable arcade patterns
Tony Hawk's Pro Skater 5
no adversarial adapting opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sunset Riders
Spawns are deterministic each credit
Tony Hawk's Pro Skater 5
minimal randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sunset Riders
Pattern memorisation for one-credit clears is the meta-game
Tony Hawk's Pro Skater 5
combo-route and score-tech optimization
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
